The Lowdown

Alright, grab your board, let's talk about what's cookin' in the water. Things are a bit tricky to start, but there's some serious juice on the horizon for the experienced crew.

We're looking at a quiet start with no real surf on offer right now. The first hint of action kicks off on Monday, September 7th, at Jaconé. It's not a beginner's day, though. We've got a solid 8ft SSW swell rolling in, with a period of 10 seconds. The wind is glassy from the NNE, making for some clean faces. The combined energy is pumping at (1137), so there's plenty of power. This is a spot for the experienced surfer, because that size is getting up there. The water is sitting at 73°, which is pretty much normal for this time of year.

Tuesday the 8th looks good too, with a 5ft S swell and a solid offshore NE wind at 12 mph. Expect clean lines and very good conditions. The energy drops a bit to (776), but it's still a sweet morning session.

Wednesday the 9th is a smaller day, with 4ft S swell, but the wind goes glassy again in the morning and turns calm in the afternoon. It'll be a fun, mellow day for cruising.

Now, let's jump ahead a bit. Friday the 11th is a real standout. We've got a 4ft S swell, but listen to this—the period jumps to 14 seconds. That's a proper groundswell, meaning long, lined-up waves with heaps of energy (673). The wind is offshore from the NE in the morning, cleaning it up perfectly. This is the kind of day you call in sick for.

The real beast, however, is set to arrive on Sunday the 13th. A massive 10ft SSW swell with a 13-second period hits, and the energy is a staggering (2667). But here's the thing—this is too big for Jaconé. The data says it's too big for this break. This is strictly for experts only, and even then, it's going to be a handful. The wind is a cross-shore from the SE at 9 mph, so it won't be perfect. Monday the 14th keeps the size up with a 8ft S swell and clean offshore winds from the ENE, another one for the experienced chargers.

After that, the swell slowly fades through the rest of the week. We get a few more decent days, like Tuesday the 15th with 7ft SSE swell and clean offshore winds, before things drop off and become more marginal toward the end of the second week. The last few days from the 20th onward are pretty small, with weak energy and fresh winds, not worth getting too excited about.

So, to sum it up: the best bet is Friday the 11th for that lovely, long-period S groundswell with clean offshores. If you're a charger, keep an eye on the 13th and 14th for the big stuff, but only if you know what you're doing.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
